Erendira Wallenda hangs by teeth and toes from helicopter over Niagara Falls

Erendira Vasquez Wallenda successfully completed an aerial stunt that involved dangling by her teeth from a helicopter over Niagara Falls.

In accordance with New York State labour law, Wallenda was tethered to the helicopter as she performed her stunt.

Wallenda broke the Guinness world record for height set by her daredevil husband, Nik Wallenda, who performed the "iron-jaw hang" in 2011 from a helicopter hovering 250 feet above a theme park in Missouri.

"I wanted to stop and go a little bit closer to the audience that I had because that's what makes you feel alive, you see people smile at you and you're hopefully inspiring other people".

Husband and wife come from world-famous circus and daredevil families.

Rebecca Wydysh, a representative for the Niagara County Legislature, presented Wallenda with a proclamation to commemorate her spectacle and declared June 15 as Erendira Wallenda Day in Niagara County.

"I respect this man so much more because it was way more windy than I thought it would be", she said. And if just being up that high wasn't enough of a thrill, she used the strength of her teeth to hang on, 50 feet above her husband's record. During the performance, she also dangled from her knees, toes, and hands.

"Hopefully we can do something together in the next five years", she said.

Helicopter pilot Paul Barth said Wallenda signaled to him to fly higher during the routine to get away from the wind. During that time, Erendira was dangling about two dozen feet - today, 300 feet.

For the sake of the performer's teeth, the stunt has evolved over the years and now the couple uses custom made mouthpieces while performing. In 2012, Nik's walk generated an economic impact of $21.5 million and $3.3 million in direct revenues to the City of Niagara Falls, Fox Newsreported. "That's unbelievable. That's awesome, '" he said.
